Find the unit rate for 521 miles in 14 hours

The unit rate for 521 miles in 14 hours is 37.2 miles per hour

Given:

Total distance travelled = 521 miles

Total time taken = 14 hours

Unit rate = Total distance travelled ÷ Total time taken

= 521 miles ÷ 14 hours

= 37.214285714285

Approximately, 37.2 miles per hour

Therefore, unit rate for 521 miles in 14 hours is 37.2 miles per hour

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
